<span>I suspect this question should read "How long does a red blood
cell live." A red blood cell lives for between 100 and 120 days. It
takes 7 days for a new red blood cell to develop from stem cells. Stem
cells are similar to base cells. They can also be seen as a general
template from which specialized cells are made. Stem cells can be taken
from a newborn baby's umbilical chord or extracted from an adult blood
donor's blood.</span>
The mixture would be :
1. Homogeneous; dissolving followed by filtration and distillation
salt dissolve in water and will be the filtrate and chalk will be the residue in the filter paper
hope this helps
Answer:
Meiosis 1 better mirrors the process of mitosis.
Explanation:
During the process of mitosis, the somatic cells of the body replicate to form two daughter cells which are identical to the parent cell. In meiosis I, two daughter cells are formed. During mitosis, diploid cells are formed. During meiosis 1 also, two diploid cells are formed. hence, these two processes are more similar as compared to mitosis II. in mitosis II, four haploid cells are made as a result of the division process.
Answer:
The plateau region has endemic population of species and the change in the ecology impacts the climate and wildlife of the area.
Explanation:
- The Edwards plateau is located in the south, central and western taxes. It bounded by faults and uplands. It has a base made of limestone.
- The plateau is home to various diverse species of plants and animals. The plateau region consists of 41 counties in geographic regions. Currently, about 2.26% of the land area is under protection as this region has experienced habitat loss of 5.3%.
Answer:
Thymine
Explanation:
Adenine is a Purines together with Guanine .
Purines always pair with Pyrimidines ; which are cyosine and Thymine.
This is a complementary base pairing that hold the two strands of DNA bases together by weak hydrogen bonds for flexibility and easily unwind during replication
Purines are larger in size beaxuae they have 2 ring structures while Pyrimidines aee smaller because of one ring structure.
Therefore two purines (Adenine and Guanine can not pair together;
It must be a Purines -Pyrimidines pairs.
Therefore Adenine must pair with Thymine and cyosine with Guanine
In RNA, Thymine are replaced with URACIL as Pyrimidines.
